It's not taking up space from another map, there's tons of space on the server for other maps. And, it's not the same as Mossrock, it's got an Upward aesthetic rather than Jungle. Some people may like to play maps with a totally different theme. Some people may actually prefer Whiterock to Mossrock. Some might enjoy learning about the origins of Mossrock, and how it originally had a totally different theme. Regardless, players are not required to switch to it if they don't want to; map rotation is based on a voting system with rtv for changing maps mid-round, so if players don't want to play Upward Mossrock, they can just vote to leave. But if players want to play Whiterock, I see no reason to not provide the option. This is like complaining about both Sunshine and Sinshine being in the game because they're the same map with different aesthetics.
